I was soldering RCA plugs onto my pre-run speaker wire late last night. Towards the end I had to squeeze into a tight space for one of the final plugs (stupidly left the hard ones till last), anyway, in my tired state I soldered the +ve to the outside and -ve to the centre pin! Now, there is less than a foot of cable to work with, so I am thinking to go to the other end of the cable where there is more slack and switch the wires to match. Would this work? My assumption being that both wires are the same and the +ve marking on one of them is just to help you identify which is which....

Okay, thanks. So what is the difference between the two wires physically? They both appear identical!

It does not make any difference as to which is connected to the center pin. You just have to make sure they are not crossed.
But if you wanted to keep all your cables uniform, as to their connections, then you would have to change the end that is wired wrong.

It's probably easier for the OP to do what is effective . He could mark the speaker wire at each end (masking tape?) noting that polarity is reversed. Not a big deal IMO.
And .... no offense to the OP, but if speaker and receiver connections have RCA connectors, it may be time to consider upgrading your speakers and receiver.
